CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 243,820, dated July 5, 1881. Application filed- October 1, 1880. (No model.)

To all whom "it may concern Be itknown that I, ISAAC P. VENDELL, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Oar-Axle Boxes, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure lis a longitudinal vertical section of an axle-box embodying my improvements. Fig. 2 is a front elevation of the same, partly in section. Fig. 3 is a detail side elevation of axle-box lid and attached pumping mechanism. Fig. at is a vertical longitudinal section of the oil-pump; Fig. 5 is a front elevation of the same, partly in section. Fig. 6 is an elevation of a modification of my invention. Fig, 7 is a vertical transverse section of the same; and Fig. Sis a plan, partly in section, of a still further modification.

My invention relates to that class of caraxle boxes in which the pumping mechanism for supplying oil to the journal-bearings is operated by the jol ting action of the car produced by traveling over the uneven portions of the track or from other causes, and has for its object to secure said pumping apparatus to a detachable frame or lid, for the purposes hereinafter more fully set forth.

My invention accordingly consists in the provision to a car-axle box of a lid or detachable frame constructed in such a manner that the oil-pumping mechanism is solely attached thereto and placed within or upon the same, whereby when the lid is removed from the axle-box the pump follows therewith, thus permitting of the application of my invention to any axle-box now in use without necessitating any alterations therein or additions thereto.

Referring to the annexed drawings, A represents the axle-box, of the usual or any suitable construction. B is the lid thereof, and is formed with a recess or chamber, 1), in which is placed a pump, 0. The latter is constructed substantially like that shown in my former patents for car-axle boxes, having an oil-passage, D, which terminates in an opening, 6, in the journal or axle-bearing E. Said pump is held in position in the chamber 6 by the lugs b l), which depend from the upper side, D of said lid and fit into recesses c c in the upper edge of said pump, so as to leave a space or interval, 0 between the said edge of the pump and the side I) of the lid B. Said pump is also provided with a branch tube, 0, which dips down into the oil-well A, as shown. Said pump 0 and oil-passage D are respectively provided with valves d and 0 as shown; or they may be located in any other suitable position in said parts.

F is the plunger, having a rod, f, which is of a less diameter than that of the plunger, so that any oil that finds its way up past said plunger will not be received upon or adhere to the rod f, but will pass off therefrom through the space 0 and drip back to the oil-well A,

thus preventing any escape of oil from the plunger-rod opening in the side I) of lid B.

To the rod f is secured a weight, G, and

surrounding said rod is a spiral spring, H, one

end of which rests upon side I) of lid B, the

other bearing against the weight Gr, thereby forming aspring-support for said weight and plunger-rod.

If desired, the upper end of the stem f may have a bearing in the standard I, projecting from or formed integral with the lid B.

The operation is obvious. which said boxes are applied travels along, the jolting of the same causes the weight G and plunger-rod to rise and fall on its springbearing H, thereby reciprocating-the plunger F to raise and force oil from the well A to the journal or axle-hearing E, the oil so pumped passing through oil-passage D, and is distributed by the ducts e e to all parts of bearing E, the surplus oil falling from the latter into the well A. The pump and its appendages being secured to lid B, no specially-formed axle-box is required, and said parts are readily removed for repairs, 850., and then as easily replaced in position.

Figs. 5 and 6 show a-modification of my invention, wherein the weight G is placed below the pump 0 and held suspended upon rods 9 g, which are secured toa cross-bar, g, aftixed to the plunger-rod f. The spring H encircles said rod, as shown. The lid B being formed with three recesses or chambers, b 2) b in As the car to 7 struction I prefer to use when new boxes are to be built; but when my invention is to be applied to axle-boxes already constructed or in use,I prefer to attach the pump to box-lids formed with a recess or recesses, as first above described.

What I claim as my invention isl. The axle-box lid B, having a chamber, 1), and depending lugs b I), in combination with pump 0, secured to said lid and held by said lugs, substantially as shown and described.

2. In a car-axle boX, a detachable lid or frame to which is secured and held supported thereby an oil-pumping device, aweight and spring attachments, arranged substantially as shown and described, whereby when said lid or frame is removed from the aXle-boX, the pumping mechanism and attachments follow therewith.

In testimony that I claim the foregoing, I have hereunto set my hand this 15th day of July, 1880.
